82 FR 31546 - Air Plan Approval; Wisconsin; Site-Specific Sulfur Dioxide Requirements for USG Interiors, LLC

ENVIRONMENTAL PROTECTION AGENCY

Federal Register Volume 82, Issue 129 (July 7, 2017)

The Environmental Protection Agency (EPA) is proposing to approve under the Clean Air Act a State Implementation Plan (SIP) revision submitted by Wisconsin on January 31, 2017, and supplemented on March 20, 2017. This SIP submittal consists of Wisconsin Administrative Order AM-16-01, which imposes a requirement for a taller cupola exhaust stack, a sulfur dioxide (SO<INF>2</INF>) emission limit in conjunction with a minimum cupola stack flue gas flow rate, and associated requirements on the mineral wool production process at the USG Interiors LLC facility located in Walworth, Wisconsin (USG- Walworth). Wisconsin submitted this SIP revision to enable the area near USG-Walworth to qualify for being designated ``attainment'' of the 2010 primary SO<INF>2</INF> National Ambient Air Quality Standards, a matter that will be addressed in a separate future rulemaking. EPA is approving AM-16-01 into the Wisconsin SIP, which makes the AM-16-01 requirements federally enforceable.

Air Plan Approval; Wisconsin; Site-Specific Sulfur Dioxide 
Requirements for USG Interiors, LLC

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve under the Clean Air Act a State Implementation Plan (SIP) 
revision submitted by Wisconsin on January 31, 2017, and supplemented 
on March 20, 2017. This SIP submittal consists of Wisconsin 
Administrative Order AM-16-01, which imposes a requirement for a taller 
cupola exhaust stack, a sulfur dioxide (SO2) emission limit 
in conjunction with a minimum cupola stack flue gas flow rate, and 
associated requirements on the mineral wool production process at the 
USG Interiors LLC facility located in Walworth, Wisconsin (USG-
Walworth). Wisconsin submitted this SIP revision to enable the area 
near USG-Walworth to qualify for being designated ``attainment'' of the 
2010 primary SO2 National Ambient Air Quality Standards, a 
matter that will be addressed in a separate future rulemaking. EPA is 
approving AM-16-01 into the Wisconsin SIP, which makes the AM-16-01 
requirements federally enforceable.

SUPPLEMENTARY INFORMATION: In the Final Rules section of this Federal

[[Page 31547]]

Register, EPA is approving the State's SIP submittal as a direct final 
rule without prior proposal because the Agency views this as a 
noncontroversial submittal and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this rule, no 
further activity is contemplated. If EPA receives adverse comments, the 
direct final rule will be withdrawn and all public comments received 
will be addressed in a subsequent final rule based on this proposed 
rule. EPA will not institute a second comment period. Any parties 
interested in commenting on this action should do so at this time. 
Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment. For 
additional information, see the direct final rule which is located in 
the Rules section of this Federal Register.

    Dated: June 20, 2017.
Robert A. Kaplan,
Acting Regional Administrator, Region 5.
